SRM 6.1 Limitations

Site Recovery Manager 6.1 offers limited support for vCloud Director environments. Using Site Recovery Manager to protect virtual machines within vCloud resource pools (virtual machines deployed to an Organization) is not supported. Using Site Recovery Manager to protect the management structure of vCD is supported. For information about how to use Site Recovery Manager to protect the vCD Server instances, vCenter Server instances, and databases that provide the management infrastructure for vCloud Director, see VMware vCloud Director Infrastructure Resiliency Case Study.

vSphere Flash Read Cache is disabled on virtual machines after recovery and the reservation is set to zero. Before performing a recovery on a virtual machine that is configured to use vSphere Flash Read Cache, take a note of virtual machine's cache reservation from the vSphere Web Client. You can reconfigure vSphere Flash Read Cache on the virtual machine after the recovery.

Site Recovery Manager 6.1 does not support the protection of virtual machines that are configured with multiple-CPU vSphere Fault Tolerance (FT). Site Recovery Manager 6.1 supports the protection of virtual machines with uni-processor vSphere FT, but deactivates uni-processor vSphere FT on the virtual machines on the recovery site after a recovery.

If you do use multi-CPU vSphere FT on virtual machines, Site Recovery Manager does not deactivate vSphere FT on the recovered virtual machines and powering on those virtual machines fails. You must manually deactivate vSphere FT on the recovered virtual machines by removing FT properties and run the recovery plan again.

If you use uni-processor vSphere FT on virtual machines, you must configure the virtual machines on the protected site so that Site Recovery Manager can deactivate vSphere FT after a recovery. For information about how to configure virtual machines for uni-processor vSphere FT on the protected site, seehttp://kb.vmware.com/kb/2109813.

vSphere Replication 6.1 supports replication of virtual machines on Virtual Volumes (vVols) with limitations. Site Recovery Manager 6.1 does not support the protection of virtual machines on Virtual Volumes, even if you use vSphere Replication as the replication technology for protection.

Site Recovery Manager 6.1 does not support NFS v 4.1 datastores.

Site Recovery Manager does not support reconfiguration of storage profile protection groups, such as changing the set of associating storage policies, group name, or descriptions. If you need to modify a storage profile protection group, you must delete it and recreate it with the new configuration.
